Metaspeed Sky Paris vs Endorphin Elite 2

The Metaspeed Sky Paris is ASICS at full race trim: a carbon racing shoe built for one job, chasing a personal best on the road. It is the cadence runner's racer, the half of the Metaspeed line tuned for runners who get faster by keeping their stride length and turning their legs over quicker, while the Metaspeed Edge Tokyo handles those who lengthen their stride. At 215g with a full-length carbon plate and a 5mm drop, it is light, aggressive and unmistakably a marathon shoe rather than a do-everything trainer. The bouncy, springy foam and stiff plate work together to roll you forward and reward a committed effort. Hold goal pace and it comes alive. Jog it easy and you will wonder what the fuss is about. In our view it sits right at the top of the carbon racing shoe pack alongside the Nike Vaporfly 4, and at £260 it is priced like the elite tool it is.

The Endorphin Elite 2 is Saucony's no-compromise carbon racing shoe, built for one job: chasing a personal best on race day. At 199g with a 39mm heel stack and a full-length carbon plate, it sits right at the top of the marathon shoe class alongside the Nike and adidas super-shoes. The star is the IncrediRUN foam, a soft, aggressively bouncy midsole that stores and returns energy when you load it at pace. This is not a do-everything running shoe. It feels twitchy and over-eager at easy jog pace, and the 6mm drop plus stiff plate ask for a confident forefoot or midfoot landing. Hold half-marathon to marathon effort and it comes alive. If you want the same Endorphin DNA for less money and more daily versatility, the Endorphin Pro 5 is the calmer, cheaper sibling. But for pure race-day return, the Elite 2 is one of the most propulsive carbon marathon shoes we have run in.
